I have tried to solve a problem to customize your own character.... this is what I have come up with, http://tbadventure.com/shapetest.swf
basically click the body section and a red line around it will form, click away from the image will change its shape. Click back on the body to release the shaping.
this can be done on the head aswell....
I know its complicated but I have no idea of how to do anything different which would do it better..
if anyone has any ideas I would be most apreciative... cheers
